Application of Trigeneration to a Multi-Unit Residential Building in Canada

Abstract

This   paper   presents   the   model   developed   to compare  a  trigeneration  system  to  existing  heating,  cooling  and electricity  generation  methods.  The  archetype  of  a  typical  13 storey   multi-unit   residential   building   has   been   simulated   in TRNSYS  with  an  array  of  commercially  available  cogeneration units.  These  units  provide  the required  heating  to  the  building through  water  storage  and  produce  electricity  as  a  subsidiary. During cooling periods heat from these units fuels a combination of  absorption  machines  modelled  especially  for  this  application. Results   show   a   reduction   of   primary   energy   consumption compared  to  an  actual  scenario.  Further  analysis  of  the  controls and storage size would be required to optimize this system.
